This page in a nutshell: If you post a legal threat on Wikipedia, you are likely to be blocked. A polite report of a legal problem, such as defamation or copyright infringement, is not a threat and will be acted on quickly.

If there are users who are involved in a legal dispute with each other whether as a direct result of incidents on Wikipedia or elsewhere, it does not constitute a valid reason to block them, as long as no legal threats are posted on Wikipedia. Editors involved in a legal dispute should not edit articles about parties to the dispute, given the potential conflict of interest.

A complaint in cases of copyright infringement is not a legal threat. If you are the owner of copyrighted material that has been inappropriately added to Wikipedia, a clear statement about whether it is licensed for such use is welcome. You may contact the information team or the Wikimedia Foundation's designated agent, or use the procedures at Wikipedia:Copyright problems.

A discussion as to whether material is libelous is not a legal threat. Wikipedia's policy on defamation is to delete libelous material as soon as it is identified. If you believe that you are the subject of a libelous statement on Wikipedia, please contact the information team at info-en-qwikipedia.org.

A court of law in Trenton, New Jersey – one of the many places you may not threaten to sue another Wikipedian

It is important to refrain from making comments that others may reasonably understand as a legal threat. For example, if you repeatedly assert that another editor's comments are "defamatory" or "libelous," that editor might interpret this as a threat to sue, even if that is not your intention. To avoid misunderstandings, use less charged wording, such as “that statement about me is false and damaging, and I ask that it be corrected." Rather than immediately blocking users who post apparent threats, administrators should first seek to clarify the user's intention.

While you may sue in a court of law, Wikipedia is not the place for legal disputes. Making legal threats on Wikipedia is uncivil and causes a number of serious problems:

It severely inhibits free editing of pages, a concept that is absolutely necessary to ensure that Wikipedia remains neutral. Without this freedom, we risk one side of a dispute intimidating the other, thus causing a systemic bias in our articles.

It creates bad feelings and a lack of trust within the community, damaging our ability to proceed quickly and efficiently with an assumption of mutual good faith.

We have had bad experiences with users who have made legal threats in the past. By making legal threats, you may damage your reputation on Wikipedia.

Attempting to resolve disputes using the dispute resolution procedures will often lead to a solution without resorting to the law. If the dispute resolution procedures do not resolve your problem, and you then choose to take legal action, you do so in the knowledge that you took all reasonable steps to resolve the situation amicably.

The Wikipedia community has a long-standing general principle that (almost) anyone is capable of reform. Accordingly, statements made in anger or misjudgment should not be held against people once genuinely and credibly withdrawn.

To prevent damage to the project, this policy removes editors who make legal threats on Wikipedia. The editor is not blocked just because "it's a legal threat", but because the block:

reduces scope for escalation of a bad situation,

reduces stress and administrative burden on the wiki,

reduces disruption to articles and the editorial environment,

prevents a situation in which someone is seeking to be a collaborative partner while setting themselves up as a legal adversary.

If these conflicts are resolved (or a consensus is reached to test whether they are resolved), then editors should be unblocked if there are no other issues that warrant a block.

The aim of this policy is to prevent legal threats being posted on Wikipedia, not to prevent article subjects or their representatives from having bad content fixed. A legal complainant may be genuinely hurt or upset. Blocking admins should encourage the user to identify factual errors in any article at issue. The user should be shown how to communicate with Wikipedia to correct errors; a link to Wikipedia:Contact us/Article problem/Factual error (from subject) may be appropriate.

Repeats of legal threats on the user's talk page have limited scope for disruption or chilling effect. The user should not be prevented from using their talk page until reasonable attempts have been made to open a civil discussion. We assume good faith while containing disruption, but the assumption of good faith is not a suicide pact; persistent or vexatious complaints may indeed lead to the user being banned and prevented from editing their talk page, but this is a last resort.
